In our tests, I discovered an unexpected behavior where calling
`item.swf_assets << swf_asset` wasn't updating computed fields
correctly.
This isn't something we actually do in-app, I think the modeling system
happened to trigger the callbacks in a way that still worked fine?
But I think this is a good idea for reliability, since caching is such
a notoriously difficult thing to get right anyway! And it makes our
tests simpler and clearer.
Specifically, `compatible_body_ids` references `swf_assets`, which, I'm
kinda surprised, *doesn't* include the newly-added asset yet when the
`ParentSwfAssetRelationship.after_save` hook runs while calling
`item.swf_assets << swf_asset`. Reloading it fixes this!
This doesn't generally happen, but did the other day when I rolled back
some of the database's SWF asset records but kept the items—and it was
a bit confusing that the homepage marked them as fully modeled!
Oh huh, when doing Rainbow Pool stuff, I put the ordering in the wrong
place! It's a sensible ordering for the Rainbow Pool page, but not so
much for the JSON view!
This is currently crashing the Rainbow Pool when the Anniversary Techo
would appear, because the asset seems to be missing? The SWF doesn't
seem to exist, nor does its manifest.
Oh right, yeah, we like to do things gracefully around here when
there's no corresponding color/species record yet!
Paying more attention to this, I'm thinking like… it could be a cool
idea to, in modeling, *create* the new color/species record, and just
not have all the attributes filled in yet? Especially now that we're
less dependent on attributes like `standard` to be set for correct
functioning.
But for now, we follow the same strategy we do elsewhere in the app: a
pet type can have `color_id` and `species_id` that don't correspond to
a real record, and we cover over that smoothly.
I only now thought through that I can scrape these instead of enter
them manually, similar to how we did our Rainbow Pool scraper… hooray!
I'm actually writing tests for stuff too, wowie!
This change was modified a bit after cherry-picking, to no longer
include the broken changes to item modeling in 9eaee4a.
(cherry picked from commit 90407403ba)
Okay so, when we reverted a buncha stuff in e3d196f, it was in response
to a bug where item modeling data was getting deleted. And I was tired,
and just took a big simple hammer to it of reverting all the modeling
refactors.
Here, we reintroduce *some* of them: the biology ones before the item
bug. And tests still pass, and in fact I can un-pending some of them!
I might also try to reapply the change where we extract it all into a
new file, but without the item parts.
```shell
git cherry-pick --no-commit 13ceec8fcc
git cherry-pick --no-commit f81415d327
git cherry-pick --no-commit c03e7446e3
git cherry-pick --no-commit 52ca41dbff
```
Also, while we're here! To restore the lost data, I:
1. Downloaded this scheduled public data backup, which was taken
thankfully the day before we updated modeling code!
https://impress.openneo.net/public-data/2024-11-03T08_15_02Z-scheduled.sql.gz
2. Trimmed it just to the section about the `parents_swf_assets` table:
dropping it, then rebuilding it from scratch.
3. Ran this modified backup SQL dump on the production server.
4. Ran the code from `db/migrate/20241001052510_add_cached_fields_to_items.rb`
to bring items' cached fields back into the correct state.
I also had to fix some errors in the item data that prevented some
items from passing the latest validations:
```rb
Item.where(rarity: "").update_all(rarity: "???")
Item.where(description: "").update_all(description: "???")
Item.where(zones_restrict: "").update_all(zones_restrict: "00000
00000000000000000000000000000000000000000000000")
```
Because we ended up with such a big error, and it doesn't have an easy
fix, I'm wrapping up today by reverting the entire set of refactors
we've done lately, so modeling in production can continue while we
improve this code further over time.
I generated this commit by hand-picking the refactor-y commits
recently, running `git revert --no-commit <hash>` in reverse order,
then manually updating `pet_spec.rb` to reflect the state of the code:
passing the most important behavioral tests, but no longer passing one
of the kinds of annoyances I *did* fix in the new code.
```shell
git revert --no-commit 48c1a58df9
git revert --no-commit 42e7eabdd8
git revert --no-commit d82c7f817a
git revert --no-commit 5264947608

```
This bug never made it into production I think, it was a consequence of
some of how I refactored stuff in the recent changes? I think??
But yeah, I refactor how we manage `SwfAsset#body_id`, to be a bit more
explicit about when and how it can change, instead of the weird
callbacks that tbqh have bit us too often…
Ah right, the callbacks in `ParentSwfAssetRelationship` don't get
called when Rails does automatic join-model management stuff. We need
the `Item` to call its `update_cached_fields` callback itself, too!
When fixing this, I found a new bug that arose, in how we infer
`body_id` for assets that fit all pets. Fixing that next!
Hmm, I think I made a mistake on `modeling_snapshot.rb:69`: I'm
assigning the *entire* `item.swf_assets` relation to *just* the assets
for the new model of it, which breaks all the other connections.
First, I'm disabling modeling. Then, I'll restore a backup. Then, I'll
write tests for that case, and fix it up!
The NC Pet Styles sentence getting broken across two lines I think
makes it too hard to notice.
Design-wise, it would be nice to just call better attention to this
feature altogether in some higher-level design-language-y way, but!
Whatever!
If you check this box, it'll keep you in a mode where saving an alt
style redirects you to the *next* one that needs labeling, until
they're all done. Useful for big drops!
Catch missing fields in validation before sending it to the DB, and
skip the Dyeworks stuff if the name is missing.
I ran into this looking into `test/trade_activity_test.rb`, which fails
right now because we try to create a boring placeholder item with
minimal fields, which Dyeworks can't call `name.match()` on!
Now, the test fails with a more helpful error about the item being
invalid. Next, I'll fix that!
Just getting this stuff out of Pet, in part because I want to start
being able to unit test modeling, and that will require stubbing out
what this service returns!
Just a bit more clarity of grouping! I'm also thinking about extracting
modeling APIs into a service file like this too, in which case I think
this would help clarify what it is.
They're not all Nostalgic anymore! Oh, how the times have changed!
This way, new ones will appear as "<New?>", until support staff come in
and label them (with our cool new tools!)
Whoops, I didn't realize this change I made to validation for the alt
style editing form, was goofing up alt style modeling!
The trick is, the validation was happening before the `before_create`
hook. Now I've reformulated these as `before_validation` hooks, so
we're not rejecting new alt styles for having no thumbnail!
